Climate Action Planning

The Agricultural Sector

An analysis conducted by CCI in 2019 estimating carbon sequestration opportunities on California’s farms and ranches, yielded a potential to reach and exceed carbon neutrality in the agricultural sector over the next two decades, if deployment of agricultural carbon sequestration practices are initiated at scale in the near-term.
 An increase in the mass of SOC in the plow layer alone of one acre of ground is roughly 4.6 metric tons of carbon.  Across 20M acres this is 93MMT C or 341 MMTCO2e.
The United States Department of Agriculture, Natural Resources Conservation Service (USDA-NRCS) has suggested 5% soil organic matter (SOM) as an indicator of a “healthy soil.”  Across the state’s roughly 20 M arable acres, elevating SOM from its current average of an estimated 2% to the recommended 5% would represent over 1.3 billion metric tons of CO2e transferred from the atmosphere to the soil organic carbon pool.

Utilizing a Carbon Farming Framework for Climate Action Planning

CCI is currently working with California RCDs and local government in Marin, San Mateo, Santa Clara, and Sonoma counties to develop methods and protocols for integrating a landscape-scale Carbon Farming framework into existing climate action planning and emergency response efforts.

The COMET-Planner tool and other peer reviewed carbon accounting methods are then used to estimate GHG reduction potential over timescales needed to reach climate action plan targets and GHG reduction goals.

County Agricultural Lands’ Estimated Carbon Sequestration Potential 

Our approach to deriving carbon sequestration potential on agricultural lands, along with the producer engagement required to arrive at those projections, not only provides critical planning information, but also creates a platform for the agricultural community to take a leadership role in responding to the climate crisis. 

 In 2020, Marin County updated its Climate Action Plan utilizing a landscape-scale carbon farming framework, working in partnership with CCI and the Marin Carbon Project. In 2021, CCI will be developing a blueprint guidance document and municipal and RCD training curriculum for our landscape-scale carbon farming approach, including methods, landowner outreach, and chapter development for climate action planning in the agricultural sector.  [Table]
